Peter talks about growing up as a fat kid, what he eats after a 20 mile run, his opinions on Chicago pizza, grilling the perfect burger, and spaghetti consumption techniques, among many other topics.

He then channels Courtney Love for a profanity-laced tirade against melted cheese. (In fairness the profanity was Courtney Love's, not Peter's. He was just channeling. But he still agrees with her conclusion.)

Also discussed: The fact that when Wait Wait producer Ian Chillag (also of NPR's How to do Everything) tried running while listening to different podcasts, his times looked like this:

Wait Wait: 7:30 per mile
The Dinner Party: 7:25 per mile
This American Life: 7:15 per mile
The Sporkful: 6:55 per mile (healthiest podcast ever!)

Plus, an 11-year-old in Texas calls in to share some cogent thoughts on burritos. Enjoy!
